We synthesized a bromo‐bridged Pd complex, which underwent as lowering the temperature a charge‐density‐wave (CDW) to Mott‐Hubbard (MH) phase transition, as confirmed by using X‐ray diffraction analysis, ESR, FT‐IR and Raman spectroscopies. The complex showed a phase‐separation phenomenon with a striped pattern over a wide temperature range, and domain propagation was observed using an optical microscope. Moreover, we observed changes in the local electronic state accompanying the phase transition by using scanning tunneling microscopy (STM)
